Biochar is an ancient technique
thatâ&#x20AC;&#x2122;s now all the rage among
growers both large and small.
A charcoal made by slow-heating
dead plants, â&#x20AC;&#x153;Biochar does not
bring fertilizer or water to plants,
but its highly porous nature tends
to increase soil resilience to water
and nutrient stresses, improving
overall plant nutrition,â&#x20AC;? explains
Caroline Masiello, PhD, a soil
chemistry researcher at Rice University in Houston. You can buy
bags of biochar alone or mixed
with compost; whichever you
choose, check that the supplier
is a member of the International
Biochar Initiative, which sets quality and environmental standards.
